Geant4 extended examples - channeling
|
|
----------------------------------------------
|
|
|
|
Examples in this directory are dedicated to various coherent effects
|
|
in oriented crystals, in particular, channeling, channeling radiation,
|
|
coherent bremsstrahlung, coherent pair production etc. as well as their
|
|
various applications.
|
|
|
|
ch0
|
|
-------
|
|
|
|
This example shows how channeling in bent crystal can be simulated
|
|
in Geant4 using G4Channeling process. The example simulates the channeling
|
|
of 400 GeV/c protons in bent Si crystal. It has been moved into channeling/ch0
|
|
from the channeling folder.
|
|
|
|
ch1
|
|
-------
|
|
|
|
This example is an easy demonstration of the minimum requirements necessary
|
|
to integrate the G4ChannelingFastSimModel and the G4BaierKatkov model
|
|
into a project in order to simulate the physics of channeling and
|
|
channeling radiation/coherent bremsstrahlung.
|
|
|
|
ch2
|
|
-------
|
|
|
|
This example is an enhanced version of ch1, providing the user with
|
|
the full functionality of both the G4ChannelingFastSimModel and G4BaierKatkov,
|
|
with parameters set up via a macro, in order to simulate the physics of
|
|
channeling and channeling radiation/coherent bremsstrahlung, and enhanced output.
|
|
The example can be exploited for a wide range of cases to study coherent effects in
|
|
a straight, bent or periodically bent crystal (crystalline undulator).
|
|
|
|
ch3
|
|
-------
|
|
|
|
This example is an easy demonstration of the minimum requirements necessary
|
|
to integrate the G4CoherentPairProduction process along with G4ChannelingFastSimModel
|
|
and G4BaierKatkov into a project in order to simulate the physics of electromagnetic
|
|
shower in an oriented crystal. The simulation includes the physics of channeling,
|
|
channeling radiation/coherent bremsstrahlung and coherent pair production.
|
|
The structure of this example is based on ch1, but with the G4CoherentPairProductionPhysics
|
|
process included, as well as different output, a different crystal material, alignment and
|
|
geometry parameters, and a photon beam as the incoming source instead of charged particles.
